Granite Basalt Gabbro

All rocks of igneous origin consist of magma or molten earth that finds its way up to.

Granite basalt gabbro.

The main difference between them is the process through which it formed and texture. Gabbro ˈ ɡ æ b r oʊ is a phaneritic coarse grained mafic intrusive igneous rock formed from the slow cooling of magnesium rich and iron rich magma into a holocrystalline mass deep beneath the earth s surface. Basalt and gabbro are both mafic igneous rocks having same mineralogy. Diabase ˈ d aɪ.

Diabase is the preferred name in north america while dolerite is. ə b eɪ s or dolerite or microgabbro is a mafic holocrystalline subvolcanic rock equivalent to volcanic basalt or plutonic gabbro diabase dikes and sills are typically shallow intrusive bodies and often exhibit fine grained to aphanitic chilled margins which may contain tachylite dark mafic glass. It means that it formed as magma cooled slowly in the crust. Gabbro is a coarse grained and usually dark colored igneous rock it is an intrusive rock.

The key difference between basalt and granite is that basalt is mostly occurring on ocean floors while granite is in the crust of the earth in all continents. Gabbro with large augite phenocrysts embedded in white plagioclase. Basalt is an extrusive fine grained igneous rock formed when the molten materials lava r. Igneous rocks with similar composition are basalt extrusive equivalent of gabbro and diabase the same rock type could be named dolerite or microgabbro instead.
